HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 559,303, dated April28, 189

Application filed June 26,1895. Serial No. 554,122. (No model.)

To aZZ whom it may concern.-

Be it known that we, ANDREW C. MILLER and EDWARD A. JOHNSON, ofCommerce, in the county of Scott and State of Missouri,

have invented a new and Improved Hay- Press, of which the following is afull, clear, and exact description.

This invention relates to certain improvements in machines or pressesfor baling or pressing hay and the like, and has for its object toprovide a device of this character of a simple and improved constructionwhich shall be adapted to be continuously operated by horse or otherpower to press the hay, &c., I 5 into bales.

The invention comprises a frame having chambers to receive the hay andhaving feeding and pressing plungers or pistons, a rotative shaft havingarms, and a lever and a connecting-rod arranged to be engaged by saidarms and connected to the pistons, so that when said shaft is rotatedsaid arms will act on said lever and the connecting-rod to move thepistons in their chambers to feed 2 5 and compress the hay.

The invention also contemplates certain novel features of constructionand combinations and arrangements of the parts of the improved press,whereby certain important advantages are attained and the device is madebetter adapted and more convenient for use than other similar forms ofpress heretofore employed, all as will be hereinafter set forth.

3 5 The novel features of the invention will be carefully defined in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi- 4ocate corresponding parts in both the li gures.

Figure 1 is a plan view of a hay-press constructed in accordance withour invention, portions of the frame thereof being shown in section tobetter illustrate the form and arrangement of the chambers and thepistons therein; and Fig. 2 is a side elevation of the device.

The frame of the machine is provided near one end with acompressioivchamber 1, of rectangular cross-section, extendinglongitudinally of it, and said frame is also provided with areceiving-chamber 2, of similar form and extending at right angles tothe said compression-chamber 1, into which it opens at its end, as seenin Fig. 1, said receiving-chamher being provided with a feed-hopper 3,extending above it, as indicated in Fig. 2.

In the chamber 2 is arranged to reciprocate a plunger or piston 5, ofrectangular crosssection, adapted when moved to carry the hay 6o fedinto the said chamber through the hopper 3 into the compression-chamber1, as indicated at 4 in Fig. 1, and in one face said piston 5 isprovided with a recess 6, extending part way through it, at oppositesides of which recess are arranged rotative rollers 7, adapted toreceive between them the tapered end of an operating-lever 8, whichextends through a slot 9, formed in the wall of the receiving-chamber 2,as clearly seen in Fig. 1, 7o

and is pivoted at 10 to a bracket 11 on the frame of the press and isprovided with a spring 12, serving to hold the piston 5 normally pressedoutward to the position indicated in dotted lines in Fig. 1. In the compression-chamber 1 is arranged to reciprocate a compressing piston orplunger 13, similar in form to the piston 5, but moving in a directionat right angles to the same, being provided with a recess 14: in itsrear face, at the forward end of which recess is pivoted at 15 a pitmanor connecting-rod 16, arranged to reciprocate in a horizontal plane,being supported at its free end on a roller 17, extending transverselyof the frame 8 5 and mounted to turn loosely in bearing studs orbrackets 18, and said pitman or connecting-rod is provided with a spring19, connecting it to the frame and adapted to hold the piston 13 at theend of its back stroke in the 0 position seen in Fig. 1.

The pitman or connecting-rod 16 is laterally movable at its rear end,and in order to limit its lateral movement and also to prevent it frombeing disengaged from the roller 5 17 we attach a second spring, 20, tothe frame of the device, having a yoke 21, encircling the said pitman orconnecting-rod 16, and carrying a roller 22, engaging the outer sidethereof, as clearly seen in the drawings.

The pitman or connecting-rod 16 is provided at its extremity with a shoe23, which may IOO be conveniently formed of sheet metal bent to form, asseen in Fig. 1, and said shoe is arranged to receive and be engaged byrollers 24:, carried on the opposite ends of a lever or beam 25, securedon a shaft 26, mounted to rotate in the frame of the machine andprovided with a pulley 27 or other device whereby said shaft and theother operative parts may be driven from any source of power in thedirection indicated by the arrow 00 in Fig. 1. The ends of the beam orlever 25 are provided with other rollers 28 below the rollers 24, whichlatter rollers are adapted to engage the end 29 of the lever S and movethe same from the position seen in dotted lines to the position seen infull lines in Fig. 1, the spring 12 acting to return said lever to itsnormal position after the passage of each of said rollers 28, as will bereadily understood.

The operation of the device is as follows: The hopper being filled withhay an d the shaft 26 set in motion, the lower roller 28 on one endthereof engages the end 29 of the lever 8 and moves the same from theposition seen in dotted lines to the position seen in full lines in Fig.1, so as to feed the hay contained in the receiving-chamber 2 into thecompression-chamber 1, the said lever and its piston being returned toits original position after the passage of said roller by means of thespring 12. As the shaft 26 rotates, the upper roller 24 on the oppositeends of the beam 25 comes to bear on the shoe 23 at the end of the leveror pitman or connecting rod 16 and moves said pitman, together with thepiston 13 carried thereby, to the position seen in dotted lines in Fig.1, thereby compressing the hay in the chamber 1, after which said roller24 slips off the shoe 23 and permits the spring 19 to return said pitmanor connecting-rod and its piston 13 to the position seen in full linesin Fig. 1. Thus it will be seen that if continuous rotati ve movement beimparted to the shaft 26 and the hay be continuously fed into the hopper3 the machine will work continuously, and it will be evident that anypower may be employed to work the said shaft, as water, horse, or steampower.

The construction of the device, as above described, is exceedinglysimple and inexpensive and is well adapted for baling hay on farms andelsewhere, being very convenient for operation and notliable toderangement of its parts. Moreover, the construction is such that whenonce the shaft 26 is set in motion little or no attention is required tobe paid to the operative parts of the device, these being altogetherself-acting.

It will be evident from the above descrip tion that some change andmodification may be made in the arrangement and construction of theimproved balin g-press without material departure from the principles ofthe inven tion, and for this reason we do not wish to be understood aslimiting ourselves to the precise form of the device herein shown anddescribed.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a hay-press or the like, the combinationof a frame having a receiving-chamber and a compressing-chamber,plungers in said chambers, a rocking lever connected at one end to oneplunger, a connecting-rod con nected to the other plunger, a rotativeshaft, and arms on said shaft to engage and alternately actuate thelever and the rod, substantially as shown and described.

2. In a hay-press or the like, the combination of a frame having areceiving-chamber and a compressingchamber, plungers in said chambers, alever pivoted on the frame with one end connected to one plunger, aretracting device for said lever, a pitman connected to the otherplunger and adapted for endwise movement, a rotative shaft, and armsthereon adapted to alternately engage and operate the said lever andpitman, substantially as shown and described.

In a hay-press or the like, the combination of a frame having areceiving-chamber and a compressing-chamber, plungers in said chambers,a rocking lever connected at one end to one plunger, a connecting-rodconnected to the other plunger, a rotative shaft and a beam on saidshaft having its opposite ends arranged to alternately engage andactuate respectively the lever and the rod, substantially as shown anddescribed.
